The PCA8547AHT/AY from NXP Semiconductors is a versatile LCD driver designed for high-contrast Vertical Alignment (VA) displays. It is AEC Q100 compliant, making it suitable for automotive applications such as instrument clusters, car radios, and climate control units.
This single-chip controller and driver can manage up to 176 elements, supporting multiplex rates up to 1:4. It features an internal charge pump for on-chip LCD voltage generation up to 9V and offers programmable temperature compensation for stable contrast across temperature ranges. The device provides selectable backplane drive configurations and a selectable display bias configuration.
Connectivity is achieved via a 400 kHz I2C-bus interface (PCA8547A) or a 5 MHz SPI-bus interface (PCA8547B). It operates with a wide digital power supply range of 1.8V to 5.5V and an LCD supply range of 2.5V to 9.0V. The PCA8547AHT/AY includes on-chip RAM for display data storage, with display memory bank switching capabilities. It also features an integrated temperature sensor with temperature readout and programmable frame frequency control from 60 Hz to 300 Hz.
The component is housed in a 64-TQFP (10x10) package and is designed for surface mounting. It operates within a temperature range of -40°C to 95°C and consumes a low current of 90 µA.
